/**
 * 核心原理
 * 1）、@EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *  1、给容器中添加了一个组件
 *      SessionRepository=》》》【RedisOperationsSessionRepository】=-》redis操作session。session的增删改查封装类
 *  2、SessionRepositoryFilter==> Filter: session '存储过滤器;每个请求过来都必须经过filter
 *      1、创建的时候,就自动从容器中获取到了sessionRepository;
 *      2、原始的request，response都被包装。SessionRepositoryRequestWrapper，SessionRepositoryResponseWrapper
 *      3、以后获取session request.gctSession();
 *      4、wrappedRequest.getSession();==>sessionRepository中获取到的。
 * 装饰者模式
